This paper describes a cryptographic protocol for merging two data sets based on identifiers without divulging those identifier records; technically, the protocol computes a blind set-theoretic union. Applications for this protocol arise, for example, in data analysis for biomedical application areas, where identifying fields (e.g., patient names) are protected by governmental privacy regulatio...

Among private set operations, the privacy preserving element reduction of a multiset can be an important tool for privacy enhancing technology as itself or in the combination with other private set operations. Recently, a protocol, over-threshold-set-union-protocol, for a privacy preserving element reduction method of a multiset was proposed by Kissner and Song in Crypto 2005. In this paper, we...

We describe the first application of two mixed finite element methods to equations glacier evolution under different simplifying assumptions, along with a framework for implicit solution coupled velocity-thickness equations. The method uses Raviart-Thomas elements velocity and piecewise constants thickness is reframing classic staggered-grid difference case unstructured triangular meshes. secon...

the right to terminate and dissolution of administrative contracts is used because of two reasons: misconducts of contractors and maintaining the requisite of public interests. in the first, the causes of it have been noted explicitly in the article of 46 of the general terms of contracts. but about the second, it is necessary to note that the article of 48 of the general terms of contracts giv...
